Do you wonder how the iPhone 5S compares to the first version? Maybe you just want to compare between 5S and 5 or 4S to see if you really want to upgrade. If you don’t have every iPhone to test your theories out on, then check out this video by Everything Apple Pro.

This YouTube video tries to show you how fast the different iPhones react. The 5S, 5C, 5, 4S and 4 all with iOS7 and the 3GS, 3G and 2G (EDGE) with their highest level of iOS software.

Things We Learned from this iPhone Speed Test

Some cases, the 2G out-performed the newer models (it turns off the fastest, for sure).

5S shows its lightning speed (when connected to Wifi)

You can see the size progression from each model

Unlocking all of them at once is pretty sweet!

It also shows that unless you want the fingerprint sensor and M7 co-processor functionality or if you want a colorful iPhone and the dynamic background of iOS7, then upgrading from the 5 or 4S might not be necessary at this time.
